In addition, distinct anticoagulants is often used to prepare plasma (eg, heparin and ethylenediaminetetraacetic acid journal.pone.0169185 [EDTA]), and these can have unique effects on plasma composition and downstream molecular assays. The lysis of red blood cells or other cell varieties (hemolysis) during blood separation procedures can contaminate the miRNA content in serum and plasma preparations. Numerous miRNAs are known to become expressed at higher levels in distinct blood cell sorts, and these miRNAs are usually excluded from evaluation to avoid confusion.Additionally, it appears that miRNA concentration in serum is higher than in plasma, hindering direct comparison of research using these diverse starting materials.25 ?Detection methodology: The miRCURY LNA Universal RT miRNA and PCR assay, as well as the TaqMan Low Density Array RT-PCR assay are amongst the most often utilized high-throughput RT-PCR platforms for miRNA detection.
